Description
Technical field
The utility model relates to fan part, and more particularly, the utility model relates to a kind of blower fan inner Rinsing unit and parts thereof of cleaning.
Background technique
In many industries such as metallurgy and chemical industry, many high-temperature services such as converter etc. all need the ventilation of blower fan air inducing, therefore; The main medium that the fan rotor impeller contacts in running is the moist flue gas of high temperature that produces in the production process such as converter smelting; Because contain moisture in the flue gas, viscosity is bigger, is adsorbed on easily on the surface and rotor air inlet runner of fan rotor impeller, and the balance of impeller is destroyed; Cause fan trouble to take place frequently, thus normally the carrying out of influence production process such as steel-making.
Be bonded in order to ensure normally carrying out of production process such as steel-making, to remove that the dust removal apparatus of laying dust becomes one of visual plant in the blower fan on the draught fan impeller.At present, domestic each steel mill's common practice is to carry out hydroblasting at the Rinsing unit that both sides, the inlet side end face and the runner of impeller are installed one group of a plurality of duck nozzle respectively.The main structure of conventional spout is to utilize common steel tube to be made into flat duckbill shape, the about 0.5～1mm in gap between the water spray duckbilled.Conventional spout is because mainly there is following shortcoming in the defective of structural design: the current of ejection are dispersive jet; The flushing area is little; There is the flushing blind area in flow action in impeller surface, causes the laying dust flushing in impeller surface and the runner unclean, still has influence on the normal operation of draught fan impeller.
Summary of the invention
Above-mentioned shortcoming to existing technology; The purpose of the utility model is Rinsing unit and the Flushing nozzle thereof that a kind of fan rotor will be provided; It has following advantage: the flushing water flow jet is even; Can effectively clean the impeller laying dust, effectively solve problems such as the dust flushing is unclean, the easy laying dust bonding of rotor surface, significantly improve the equipment safety operation cycle.
For this reason; One of technical solution of the utility model is a kind of Rinsing unit of fan rotor; It comprises water supply line, and said Rinsing unit comprises the shroud jet pipe that kibli machine rotor inlet side card is installed, and this shroud jet pipe one end comprises the joint that connects water supply line; This shroud jet pipe the other end is connecting the shower nozzle that has nozzle, and this nozzle comprises width expansion from inside to outside but four rib guide channels of cross-section area and reduced height.
Find that originally traditional duck nozzle guide channel is lack of standardization; So that traditional spray washing flow point looses unable and is difficult to effectively clean the fan rotor impeller; To the required current characteristics of hydro-peening vane rotor; The Rinsing unit of the utility model creatively adopts width expansion from inside to outside but four rib guide channels of cross-section area and reduced height; The straight nozzle of this extroversion " splayed shape " makes the hydro-peening current even, continuous, straight, strong, and the current edge that the nozzle of outwards width expansion makes each nozzle come out is overlapped, the plane current waterfall of formation width stack, thereby can effectively rinse the laying dust of fan rotor impeller surface well.
Probationary certificate, the Rinsing unit of the utility model fan rotor make the water-spraying flowing pressure bigger, have avoided occurring current scattering and non-uniform phenomenon, have eliminated current flushing blind area, and developing result far surpasses conventional spout; After being applied in claimant enterprise once dust collection of converter blower fan, initiative fan rotor safety on line surpasses 28 months working time, substantially exceeds 20 days～60 days operation period of conventional fan, has created leading domestic level.This shows the utility model Rinsing unit handle converter dust-removing fan rotor ash deposit and slag buildup this in the industry in the practical application of a difficult problem, have very good technology economic and broad prospect for its application.
For further enlarging the hydro-peening zone, strengthening developing result, the utility model also comprises following improvement:
Said Rinsing unit also comprise stretch into and kibli machine rotor runner in the runner jet pipe; This runner jet pipe one end comprises the joint that connects water supply line; This runner jet pipe the other end is connecting the shower nozzle that has nozzle, and this nozzle also comprises width expansion from inside to outside but four rib guide channels of cross-section area and reduced height.
Said Rinsing unit comprises 2 shroud jet pipes and is located at card both sides, fan rotor inlet side symmetrically that the shower nozzle of shroud jet pipe is provided with 6-10 nozzle of a row.
The shower nozzle of said runner jet pipe is provided with 1-3 nozzle of a row.
The afterburning effect of geometrical construction, water conservancy diversion for further optimizing four rib guide channels improves the shower nozzle volume utilization, strengthens developing result, and the utility model also comprises following improvement:
The cross section of said four rib guide channels is a rectangle.
The width of said four rib guide channels is expanded from inside to outside and has been formed the isosceles trapezoid of going to the bottom outside; The height of said four rib guide channels dwindles from inside to outside and has formed the isosceles trapezoid of going to the bottom interior.
The outer open area of said shroud jet pipe nozzle is the 7-9% of open area in it.
The outer open area of said runner jet pipe nozzle is the 20-30% of open area in it.
Correspondingly, another technical solution of the utility model is a kind of Flushing nozzle of fan rotor, offers nozzle on it, and said nozzle comprises width expansion from inside to outside but four rib guide channels of cross-section area and reduced height.
Obviously, the nozzle chamber that current get into the utility model Flushing nozzle through jet pipe, standard ground narrows gradually because nozzle chamber is level and smooth, and current are squeezed, and the pressure of current sprays and goes out from " one " font collar extension thereupon strengthening the back; Simultaneously owing to laterally be " Eight characters " shape trapezium structure about nozzle; Making the current of each nozzle ejection is " fan-shaped " shape; And cross with the current of adjacent ejection and to form complete continuous current waterfall, rush at impeller surface, spraying current can cover whole impeller end face in complete nothing left ground, thus the flushing blind area of having eliminated traditional flushing current; Make the thoroughly clean more of fan rotor flushing, the developing result of nozzle is better.
The afterburning effect of geometrical construction, water conservancy diversion for further optimizing four rib guide channels improves the shower nozzle volume utilization, strengthens developing result, and the utility model shower nozzle also comprises following improvement:
The width of said four rib guide channels is expanded from inside to outside and has been formed the isosceles trapezoid of going to the bottom outside, and it dwindles highly from inside to outside and has formed the isosceles trapezoid of going to the bottom interior; The outer open area of said nozzle is the 7-30% of open area in it.
In a word, the utility model Flushing nozzle flushing water flow jet is even, can impel and more effectively clean the impeller laying dust, more effectively solves problems such as the dust flushing is unclean, the easy laying dust bonding of rotor surface, thereby significantly improves the equipment safety operation cycle.
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.
